The Role of Competition and Predation in Ecology - Competition and predation are two key factors that affect the stability of an ecosystem, such as a lake. There are three theories on the affects of competition. Competition may lead to competitive exclusion, stable coexistence, or niche differentiation. It has been shown that in marine environments, species are strong competitors for both light and nutrients and thus competition leads only to competitive exclusion (Passarge et al. 2006). The competitive exclusion principle states that if two species compete for the same resource in the same location, then one of those species will go extinct because one species will be the better competitor (Jenson 2010)....   [tags: ecology]

The Impact of Sea Otters on Marine Ecology - Sea otters (Enhydra lutris) are marine mammals capable of spending their entire lives in water. Being carnivorous in nature, they feed on sea urchins, crabs, fishes, mussels and clams. They are referred to as keystone species due to their profound impact on marine ecology. The interaction between sea otters, sea urchins and kelp forests has been studied as a model of the impact of predator-prey interaction on community ecology. Sea otters are keystone predators, whose presence has a far-reaching influence on the marine food web by affecting the population of sea urchins in particular, and kelp forests & other marine organisms in general....   [tags: Ecology ]

Theories of Social Ecology - All three theories by Heidegger, Bookchin, and Naess are based on the normative assumption: humans perceived themselves as being distinct from a world that unites both humans and non-humans. To better understand the distinguishments that each author makes in his theory, I will reconstruct each of their assumption. After that, we will explore the rational fashioning of integrative ways and the problems that it raises. In conclusion, there may be a reiteration of the assumption in our effort to act ethically according to the ecosystem....   [tags: Social Ecology]

The process plays a much more important role than it is usually credited with. Bioeroding species, consisting of many different types of organisms that act on the environment in a seemingly endless variety of ways, interact with the ecosystem and with each other as part of the reef growth and degradation cycle.

Once a population has reached this level, it then tends to fluctuate; however some populations even tend to encounter a steep population decline until the population density is in some sort of equilibrium with the environment (Smith, 1966). In a nutshell, the logistic model of population growth incorporates the concept of carrying capacity into the previously developed model of exponential growth - the result is a decrease in the rate of population growth as the population size approaches the carrying capacity (Smith & Smith, 2012)....   [tags: Growth, Development]

Guas of Harvard University (Stillman, 2010). Using this view, the organization and its employees are like the structure of a living organism. The environment of the organization contributes to the establishment of the power that it will come to acquire or lose over its life....   [tags: Ecology, Agencies, Paths] 920 words

Water Shortage in the Middle East - Water is the main source of life on the Earth. It is vital for normal existence and functioning of organisms. Earth is sometimes called “water planet.” But, in fact, the number of freshwater is limited. “Only about 2 percent of the planet's water is fresh.” (How much water is there on Earth?) This water is not enough even to meet daily needs of mankind. According to World Health Organization, “a lack of water to meet daily needs is a reality today for one in three people around the world.” (2009) In the Middle East the situation is especially hard....   [tags: Environmental Science Ecology]

Amphibians - Amphibian means “double life” referring to the fact that most adult amphibians live on land while embryos need water to survive. Some amphibians have been around since the Jurassic age; however the numbers of these long alive animals are declining around the world (Amphibia). As of 2010, 32% of the world’s 6600 amphibian species were threatened with extinction (Hayes, Falso, Gallipeau, Stice 2010). There is no single cause of the amphibian decline, but it seems that habitat loss, like deforestation, is the main reason along with human impact in terms of urbanization, forest fragmentation, predation, human exploitation, pathogens and climate change (Hayes, Falso, Gallipeau, Stice 2010)....   [tags: Ecology ]

The Green Gap: Exploring the Divide Between Ecological Thinking and Acting - Most Americas with any media exposure know the ecological damage our society is doing to Earth, yet we have accomplished almost nothing to mediate it. This gap between knowing and acting seems counterintuitive. Commonsense tells us that once we know something is bad, steps are taken to prevent it. Prevention is all the more relevant because Earth is a dynamic system where impacts on one side of the planet are felt on the other. As my mother always quoted to me, “Commonsense ain't all that common.” This paper looks at the potential rationals of why we often believe in the ecological damage we are doing, but fail to act to fix it; the “Green Gap” as it were....   [tags: Ecology]

Policy Evaluation of the REDD Mechanism in the Congo - Introduction Deforestation in tropical forests has gained salience in public debate on climate change mitigation policies. Such salience stems from the negative externalities caused by deforestation, such as the release of greenhouse gases emissions, the loss of biomass, forest degradation etc. Recent research on CO2 emissions point out that tropical deforestation represents about 15 to 17 percent of anthropogenic emissions of carbon dioxide (CO2) . To curb the emission of greenhouse gases emissions from tropical forests, the parties to the United Nations Framework on Climate Change Convention have initiated a mitigation policy called “REDD+” (Reduction of greenhouse gases emissions from def...   [tags: Ecology ]
